Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
This splits autotools, depends build, and travis changes out of #10102, so code changes and build system changes can be reviewed separately.

Travis is consistently failing on s390 due to out of disk space issues,
which causes false positives. Disable the s390 build for now until
this is fixed some other way.

fa5d709fb2 ci: Move wrap-qemu into separate script (MarcoFalke)
Pull request description:
Now that the ci system no longer propagates files from the docker container back to the host, the wrap-qemu script is broken.
To fix it, every statement in the script needs to be executed in the docker (with `DOCKER_EXEC`). Instead of juggling with triple escape sequences like `\\\"`, just move the script to a separate file and call it with `DOCKER_EXEC`.
Also, fix a bunch of other bugs that prevent running the ci system in qemu
See the `ci/README.md` on how to test. TLDR: Can be tested with (replace `arm` with `s390x` to run the s390x build):
```
FILE_ENV="./ci/test/00_setup_env_arm.sh" MAKEJOBS="-j9" ./ci/test_run_all.sh
```

711e0449cf ci: Remove trusty build (Hennadii Stepanov)
7f3ae22468 ci: Add CentOS 7 build (Hennadii Stepanov)
Pull request description:
Arguably, CentOS is the most conservative distro of all the popular ones. Thus, it could be a good way to check the Bitcoin Core compatibility with aged dependencies.
Currently, CentOS 7 has:
- Berkeley DB == 4.8.30
- Boost == 1.53.0
- GCC == 4.8.5
- libevent == 2.0.21 < minimum required [2.0.22](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md), but tests passed
- MiniUPnPc == 2.0
- Python == 3.6.8
- qrencode == 3.4.1
- Qt == 5.9.7
- ZeroMQ == 4.1.4
~Please note that this PR is based on the bugfix #17634.~
Also trusty build has been removed for the following reasons:
- https://github.com/bitcoin/bitcoin/issues/17628#issuecomment-559448201:
> Maybe it'd make sense to replace Ubuntu Trusty with Centos 7 as the "check ancient backward compatibililty" Travis run. It's supported until 2024, apparently.
- https://github.com/bitcoin/bitcoin/pull/17635#discussion_r354811792:
> Our travis is currently running at its limit and this doesn't seem like it is adding a lot new coverage compared to the other builds.

Pull request description:
Some minor cleanups:
* Remove unused and unmaintained extended_lint to avoid ci bottlenecks and waste of CPU
* Move all folders that hold temporary ci files to the ci scratch dir (except for the build dirs)
* Add some documentation to folders and remove the `BASE_BUILD_DIR` alias for the root directory
* Fixes#17178 by removing `cd`

Pull request description:
This keeps the cross-compilation to make it easy to run the ci on non-arm hardware. To run this locally in qemu-user as it used to be, just `export QEMU_USER_CMD="qemu-arm -L /usr/arm-linux-gnueabihf/"`.

0c78e49be3 tests: Switch one of the Travis jobs to an unsigned char environment (-funsigned-char) (practicalswift)
Pull request description:
Switch one of the Travis jobs to an unsigned char environment (`-funsigned-char`).
This will help us catch errors due to code written under the assumption that `char` has the same value range as `signed char`.
The signedness of `char` is implementation-defined.
Example:
```
$ uname -a
Linux […] x86_64 x86_64 x86_64 GNU/Linux
$ cat foo.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = (unsigned char)c;
std::cout << i << "\n";
}
$ clang++ -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -fsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -funsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ cat bar.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = c;
std::cout << i << "\n";
}
$ clang++ -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -fsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -funsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
255
```
`gcc` chars:
* signed: alpha, hppa, ia64, m68k, mips, sh, sparc, x86
* unsigned: arm, powerpc, s390
About `-funsigned-char`:
> Let the type "char" be unsigned, like "unsigned char".
>
> Each kind of machine has a default for what "char" should be. It is either like "unsigned char" by default or like "signed char" by default.
>
> Ideally, a portable program should always use "signed char" or "unsigned char" when it depends on the signedness of an object. But many programs have been written to use plain "char" and expect it to be signed, or expect it to be unsigned, depending on the machines they were written for.
>
> This option, and its inverse, let you make such a program work with the opposite default. The type "char" is always a distinct type from each of "signed char" or "unsigned char", even though its behavior is always just like one of those two.
